Creatine Hydrochloride

You’ve probably heard about Creatine before – it’s been used as a gym supplement since the 1990’s, making it one of the most reliable ingredients on the market.

Creatine Hydrochloride is a form of Creatine, which is proven to boost your strength and endurance – you’ll feel the difference towards the end of sets and your overall workout.

It’s believed that Creatine Hydrochloride works better in lower doses than Creatine Monohydrate, but this isn’t the case. Creatine Monohydrate is the most effective form of Creatine and there’s been tons of research proving it’s the best.

Don’t get us wrong – Creatine Hydrochloride is still an effective ingredient, but Creatine Monohydrate is simply more reliable due to the countless studies conducted on it.

Ingredient rating:

Creatine Monohydrate is the most effective form of Creatine.

But Hydrochloride is still beneficial.

Beta-Alanine

Jym Supplement Science has made a mistake by adding this ingredient, but they’re not the only ones doing it. You’re probably thinking, why?

Well, many companies use Beta-Alanine as it’s shown to improve muscular endurance. However, it can cause paresthesia when consumed in doses over 0.8g-1g (800mg-1,000mg).

Paresthesia is a tingling on the skin of your face, chest, hands, and extremities – it’s not life threatening, but it’s uncomfortable enough to ruin your training session.

Citrulline Malate

Citrulline Malate is a combination of L-Citrulline and Malic Acid – L-Citrulline boosts nitric oxide levels, while Malic Acid helps boost energy levels, making this ingredient a great addition to any pre-workout.

It works by turning into L-Arginine in your kidneys, where it raises your nitric oxide levels and dilated your blood vessels (vasodilation). This leads to an increase in blood flow, resulting in you experiencing intense muscle pumps while lifting weights.

However, if you’re thinking, why not take L-Arginine directly? Here’s why – L-Arginine has a poor absorption rate, meaning it fails to raise your nitric oxide levels when orally supplemented. On the other hand, Citrulline Malate has a great absorption rate and is reliable in delivering muscle pumps and a boost in energy.

Jym Supplement Science has dosed Citrulline Malate perfectly at 6,000mg – its optimal dose is between 6,000mg-8,000mg, so you’ll be sure to experience its full benefits.

Beetroot Extract

This encourages vasodilation (widening of your blood vessels), which results in intense muscle pumps while you lift weights. Not only does this enhance your endurance in the gym, but it also promotes muscle growth.

BCAA (Leucine, Isoleucine, and Valine)

BCAAs (Branched Chain Amino Acids) are found in any food containing protein, such as eggs and meat. For this reason, you don’t need to supplement BCAAs.

Studies have shown that BCAAs promotes endurance and fatigue, but you can consume enough of it through a well-planned diet. However, it’s beneficial if you’re a vegetarian or vegan.

Ingredient rating:

Supplementation isn’t necessary – you can consume enough through a well-planned diet.

But it’s beneficial to vegetarians or vegans (as they obviously don’t eat meat).

Not needed in a pre-workout supplement.

Caffeine

This is one of the most beneficial and safe nutrients out there. Caffeine is used in countless products worldwide on a daily basis, like tea and coffee.

As well as being in some of your favorite hot drinks, it delivers benefits such as improved strength, endurance, and mental function (memory, focus, reaction time) in the gym – making it perfect in a pre-workout.

Pre Jym contains the upper limit on Caffeine, with the recommended daily allowance (RDA) set at 400mg – Pre Jym contains 300mg, meaning you may have to avoid coffee and tea throughout the day if you’re using this product.

We recommend looking for a pre-workout containing 150-200mg of Caffeine per serving, to avoid unwanted side effects like jitters and energy crashes.

Side Effects

Pre Jym contains a few ingredients that can cause side effects, such as Beta-Alanine, Betaine, Alpha-GPC, and Huperzine A. We recommend staying away from these ingredients to avoid any unwanted side effects.

Here’s a list of the potential side effects from using Pre Jym:

Paresthesia – a tingling on the skin of your face, chest, hands, and extremities (Beta-Alanine)

Pre Jym Review Conclusion

Pre Jym is a decent product and we can see why it’s been given good reviews elsewhere – it contains optimal amounts of Citrulline Malate and Creatine Monohydrate, which is rare to find in pre-workout supplements.

However, Jym Supplement Science should’ve left out some ingredients, such as Beta-Alanine, Betaine, Alpha-GPC, and Huperzine A – to keep you safe from unwanted side effects.

Ultimately, the list of potential side effects, and some of these ineffective ingredients for a pre-workout, have lowered Pre Jym’s overall score.

Bottom Line: You should look for a product containing more key pre-workout ingredients, such as L-Theanine – L-Theanine works in synergy with caffeine to form a ‘smart-caffeine’, giving you enhanced benefits of caffeine (improved strength, endurance and mental function), without the risk of side effects like jitters and energy crashes.
